1. Irola yeinki
I-inki roller ibhekisa kuzo zonke ii-cot kwinkqubo yokubonelela nge-inki. Umsebenzi we-inki roller kukuhambisa i-inki yokushicilela kwipleyiti yokushicilela ngendlela yobuninzi nefanayo. I-inki roller inokwahlulwahlulwa ibe ziindidi ezintathu: ukuthwala i-inki, ukudlulisa i-inki kunye nokuxhomekeka kwipleyiti. I-inki carrier roller ikwabizwa ngokuba yi-inki bucket roller. Isetyenziselwa ukukhupha i-inki yobuninzi kwi-inki bucket ngalo lonke ixesha ize emva koko iyidlulisele kwi-inki transfer roller (ekwabizwa ngokuba yi-uniform ink roller). I-inki transfer roller ifumana ezi inki kwaye izisasaze ngokulinganayo ukuze zenze ifilimu ye-inki efanayo, ethi emva koko idluliselwe kwi-plate backup roller, enoxanduva lokusasaza i-inki kwipleyiti ngokulinganayo. Ukuza kuthi ga ngoku, umsebenzi we-inki roller ugqityiwe. Ukusasazwa kwe-inki ngokulinganayo kugqitywa kancinci kancinci kwinkqubo yokudlulisa ngokulandelelana kwee-cot ezininzi. Kule nkqubo, ukongeza kwii-cot, kukho ii-hard rollers kunye ne-inki ebizwa ngokuba yi-ink rollers. Kwi-offset press, ii-cot kunye nee-hard rolls zihlala zicwangciswa ngamaxesha athile, zenza i-collocation ethambileyo neqinileyo, olu lungiselelo lunceda ngakumbi ekudlulisweni nasekusasazweni kwe-inki. Umsebenzi we-inking roller unokomeleza ngakumbi ukusasazwa kwe-axial ye-inki. Xa isebenza, i-inking roller inokujikeleza kwaye ihambe kwicala le-axial, ngoko ke ibizwa ngokuba yi-inking roller.
2. Irola yokudambisa
Irola yokufunxa amanzi yirola yerabha kwinkqubo yokubonelela ngamanzi, efana nerola yeinki, kwaye umsebenzi wayo kukuthutha amanzi ngokulinganayo ukuya kwipleyiti yokuprinta. Iirola zokufunxa amanzi ziquka ukuthuthwa kwamanzi, ukudluliswa kwamanzi, kunye nokuprinta. Okwangoku, kukho iindlela ezimbini zokubonelela ngamanzi kwiirola zamanzi, enye yazo kukubonelela ngamanzi okuqhubekayo, exhomekeke kwirola yepleyiti engenasigqubuthelo sevelvet yamanzi, kwaye ukubonelela ngamanzi kufezekiswa ngokulungelelanisa isantya serola yebhakethi yamanzi. Indlela yokuqala yokubonelela ngamanzi yayingakhawulezi, eyayixhomekeke kwirola yepleyiti egqunywe ngesigqubuthelo sevelvet yamanzi, kwaye irola yamanzi ijikeleziswe ukuze inike amanzi. Indlela yokubonelela ngamanzi okuqhubekayo ifanelekile ekuprintweni ngesantya esiphezulu, kwaye indlela yokubonelela ngamanzi engakhawuleziyo iye yatshintshwa kancinci kancinci.
3. Ulwakhiwo lwerola yerabha
I-roll core kunye nezinto zerabha ezisetyenziswa ngaphandle zahlukile ngokuxhomekeke kwinjongo.
Ulwakhiwo lwe-roller core lunokuba lukhuni okanye lube lukhuni ngokuxhomekeke kwisicelo. Ubunzima be-roller yerabha buhlala bufuneka, buchaphazela ubunzima obuchasene nomatshini, kwaye emva koko buchaphazela ukuzinza kokungcangcazela ngexesha lokusebenza.
Uninzi lweerola zerabha zomatshini wokuprinta we-offset ziirola ezingenanto, eziqhele ukwenziwa ngeemibhobho zentsimbi ezingezizo zefeng, kwaye iintloko zeshaft kumacala omabini zidityaniswa kwiipayipi zentsimbi iyonke. Nangona kunjalo, kungekudala, zenziwe ngezinto ezingezizo zesinyithi, ezifana neeplastiki eziqinisiweyo zefayibha yeglasi kunye nezinye izinto zepolymer, injongo yazo kukunciphisa ubunzima kunye nokuphucula isantya sokusebenza kunye nokuzinza. Umzekelo, oomatshini abajikelezayo abakhawulezayo banemizekelo yesicelo.
4. Izinto ezikwimaleko yeglu
Izinto zerabha ezisetyenziswayo zinefuthe elikhulu ekusebenzeni nasekusemgangathweni kwerola yerabha. Kufuneka kukhethwe izinto zerabha ezahlukeneyo kwiindawo ezahlukeneyo zokusetyenziswa, ezinje ngokumelana nokuguguleka, ukumelana nobushushu, ukumelana nokubanda, ukumelana ne-asidi, ukumelana netyuwa, ukumelana namanzi njalo njalo. Kukwakho nobunzima, ukuthamba, umbala, njl.njl., zonke ezibekwa phambili ngenxa yendawo yokusetyenziswa kunye neemfuno zabathengi.
